Multibeam bathymetric image of the King George shipwreck in Bermuda color coded with depth such that the warmer colors (red, orange, etc.) represent shallower depths, while the colder colors (purple) correspond to deeper depths. This dredge ship was intentionally sunk in 18 m water depths of the north lagoon in 1930. Image courtesy of Rikk Kvitek, Bermuda Deep Water Caves 2011 Exploration, NOAA-OER.
